Input file ${inputPath} does not exist.

Error message

Input file ${inputPath} does not exist.

What it means

convertAudioToWav checks fs.existsSync(inputPath) before invoking ffmpeg and throws if the file is missing, guarding ffmpeg from receiving a nonexistent input. The message interpolates the offending path.

Solutions

1. Resolve the path to an absolute form and verify existence with fs.statSync before calling convertAudioToWav.
2. Eliminate races where another process deletes the temp file.
3. Confirm the file lives under the intended base directory.

Example fix

// before
async convertAudioToWav(inputPath, outputPath) {
  if (!fs.existsSync(inputPath))
    throw new Error(`Input file ${inputPath} does not exist.`);

// after — caller pre-validates with statSync (handles broken symlinks too)
const inputPath = path.resolve(tmpDir, filename);
if (!fs.statSync(inputPath).isFile()) throw new Error(`Missing source: ${inputPath}`);
await ffmpeg.convertAudioToWav(inputPath, outputPath);

const fs = require("fs");
function inputReady(p) {
  try { return fs.statSync(p).isFile(); } catch { return false; }
}
// if (!inputReady(inputPath)) skip / report;

try { await ffmpeg.convertAudioToWav(inPath, outPath); }
catch (e) {
  if (e.message.startsWith("Input file") && e.message.includes("does not exist")) {
    /* report missing source, skip */
  }
  throw e;
}

When it happens

Trigger: Caller passes a path where fs.existsSync returns false — deleted file, wrong path, relative path resolved against the wrong cwd, or a race where the file was removed between queuing and processing.

Common situations: Temp file already cleaned by another worker; path typo; file on a different mount/container; relative path mis-resolved.
